On April 9, 2015, StarWars.com announced that another unfinished, four-episode story arc, "Bad Batch," would be screened in story-reel form at Celebration Anaheim.[5] The arc's writer, Brent Friedman, previously released a good amount of information on the episodes via his Twitter account.[6][7]

The "Bad Batch" arc was originally intended to be the premiere for a seventh season. The episodes were first screened in story reel form at Celebration Anaheim and were released on StarWars.com shortly thereafter.

In March 2016, Lucasfilm Story Group'sPablo Hidalgo stated that there were 13 story arcs left after the release of the sixth season.[18] First-draft scripts had been written for seasons 7 and 8 prior to the series' cancellation.[19] Brent Friedman confirmed via Twitter that each arc was four episodes long.[20] Hidalgo also confirmed that production season 5 had 25 episodes while production seasons 6 and 7 had 24 episodes each.[8] Although scripts for these stories exist, they're not canon unless an official release is made, even if other media refers to these events.[source?]

A four-episode arc with production codes 6.05–6.08[23] was to follow Ahsoka Tano after her decision to leave the Jedi Order. This arc was to show some of her first adventures in the underworld where she met a scoundrel named Nyx Okami, who she developed a close relationship with.[24] Ahsoka's character was challenged when she got involved with the underworld and the Pyke Syndicate but had to resist her Jedi teachings for her own safety.[24]

A four-episode arc written by Matt Michnovetz[25] with production codes 6.17–6.20 starred Yoda and the Bad Batch on Kashyyyk.[26] At the "Untold Clone Wars" panel at Celebration Anaheim, Dave Filoni talked about the plot of the arc. He revealed the the characters would ride on giant ape lizards that were holy to the Wookiees. In one scene, Tarfful would ask the tree spirits for permission to go into battle against the enemy, which was a Trandoshan and the Separatist Alliance. To get the enemy out of some of their cities, they would have to burn some of the trees. The clones had no problem with it, but it was upsetting to the Wookiees. A part of the arc would be about the clones and the Wookiees finding a common ground to fight the Separatists. Some of Yoda's troopers would have his head silhouette on their helmets, and Echo would now be part of the Bad Batch squad. A story-reel clip was shown at the panel, which showed the Bad Batch and other Wookiees battling a new beast that was based on Kinraths from the Star Wars: Knights of the Old Republic game.[22] Only parts of the four episodes of the arc were made into animatics before the series' cancellation.[27] Dave Filoni revealed at Celebration Europe II that Yoda would be in the arc to give credit to the line "Good relations with the Wookiees I have" from Revenge of the Sith.[28] Matt Michnovetz revealed that Chewbacca would have played a huge role,[29] and that the arc would have contained some references to The Star Wars Holiday Special.[30]

Brent Friedman wrote the script for a four-episode arc starring Rex and R2. This story showed the ground forces of the Clone Army getting into an argument with the pilots, and their astomechs, including R2-D2. This arc featured Rex and R2, where Rex flew a starfighter with R2 as his copilot. They would crash and be stranded together on one of the moons of Ryloth,[22] where most of the episodes would take place.[31] Rex and R2 reprogrammed a B2 super battle droid that they would grow attached to,[32] and at some point Rex was injured.[33] Friedman commented that the arc started out light and fun but then went to "some very unexpected and dark places."[34]

This story would have involved the Yuuzhan Vong in a very minimal way. A scout ship was trying to assess the strength of the Republic and what Jedi were. Pablo Hidalgo commented that it was a creepy story and would have been like an X-files episode with an alien-abduction event.[22] To better align with George Lucas' description of the Force, the Vong did not have any Force immunity in this story.[35] Pablo said the story never got into the origins of the Vong, but that they probably were from another galaxy.[36]

This story would be about what lay beneath the Jedi Temple, similar to how churches were often built on the previous religious center. Different Force-user temples, and maybe even a Sith shrine, would be beneath. There would be giant skeleton Kaiju down there. Ahsoka discovers a threat in the underworld of Coruscant and makes her way back to the Jedi order to warn them. She, Obi-Wan Kenobi and Anakin Skywalker sets out to rescue Master Yoda from the Sith shrine. The arc would also have featured Darth Sidious trying to break into the Holocron Vault of the Jedi Temple, but Ahsoka would hinder his progress.[24]

This story had productions codes 7.17–7.20 and would have starred Padmé Amidala working against Chancellor Palpatine's prolonged stay in office. In episode 7.19 Padmé and Anakin Skywalker returned to Mon Cala to meet with PrinceLee-Char once again. While there, they found out that the leader of the Quarren, Nossor Ri, had been murdered, and Tikkes had been appointed provisional leader in his place. Padmé hoped to gain support from the Quarren to remove Palpatine from office. The Quarren SenatorTundra Dowmeia explained to Padmé that their government was gridlocked and unable to function. They would meet with Tikkes, who expressed frustrations with Palpatine.[37]
